Drafted in the 1st round (16th overall) by the Arizona Diamondbacks in 2014 (signed for $2,700,000)

Toussaint might have the least baseball experience of any top draft prospect, yet arguably the highest ceiling of any high school pitcher. He's of Haitian descent and was a soccer player who began playing baseball as a teenager. He gained note in scouting circles as an underclassman by running his fastball up to 97 mph with a hammer breaking ball. While his control was below-average on the showcase circuit last summer, he showed all the raw material. Then he made significant strides as a pitcher this spring. Although he sat 90-93 mph at the National High School Invitational in frigid weather, Toussaint has had numerous starts where he sat 93-96 mph, touching 97 with plus life. He has elite arm speed and whip-like arm action with long arms. His curveball shows flashes of being a plus-plus offering and potentially the best in the class. His hammer, according to TrackMan, had the highest spin rate of any Perfect Game All-American. Toussaint's changeup improved dramatically and has at least plus potential. Control will be his biggest question mark, as he has struggled to consistently fill up the strike zone. But his elite, quick-twitch athleticism could go toward allaying those concerns, as he is probably the best athlete in the pitching class. Toussaint also has a great pitcher's body at 6-foot-2, 198 pounds with a high waist, long extremities and large hands. He is also young for the class and won't turn 18 until after the draft.
